Description

RELATED CASE

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/419,567 tiled on Nov. 9, 2016 and incorporates said provisional application by reference into this document as if fully set out at this point.

FIELD OF THE INVENTION

The present invention relates to systems, apparatuses and methods for remotely activating and/or controlling operations in outdoor cookers and smokers and to the use of geo-fence requirements and parameters in relation thereto.

BACKGROUND OF THE INVENTION

Recently, gas grills have been proposed or developed which are equipped with semi-automated heating and/or cooking control systems which can he digitally connected to Smart devices such as tablets, cell phones, and the like. An example of one such system for an outdoor grill is shown and described in US2016/0037966. In the grill control system described in US 2016/0037966, each of the individual burners contained in the grill is equipped with its own independent, automated electric control valve and temperature instrument system for controlling the rate of gas flow delivered to the burner.

Unfortunately, although systems have been proposed for remotely monitoring and/or controlling the cooking operations performed in outdoor cookers, these systems have not included means for accurately and consistently ensuring that the user is sufficiently close to the outdoor cooker before allowing the user to remotely activate or control certain critical operations such as, for example, igniting the burner heating elements.

In contrast, when using a standard, non-automated outdoor gas grill or cooker, it has been necessary that the user be physically present at the cooker in order to open the gas flow valves and ignite the burner elements. This has allowed the user to verify that the cooker is in safe condition to be ignited. In other words, by being present at the cooker, the user has been able to physically observe, for example, whether the lid is open, whether there are any flammable materials in close proximity to the cooker, whether the cooker is too close to a wall of the user's home or to a fence or other structure, whether the cooker needs to be moved out from under an awning or other overhead structure, whether there are any young children in close proximity to the cooker, whether a storage covering for the cooker has been properly removed, whether anyone else may be standing close to or looking inside the cooker, etc.

When using cell phone or enabled smart phones or other smart devices for remotely activating and/or controlling outdoor cookers, the user can potentially be positioned any distance away from the outdoor cooker. Moreover, even when using shorter range radio frequency or Bluetooth enabled phones or remotes, the range of such systems is typically sufficient such that the user would still be able to remotely ignite the outdoor cooker even though the user might be indoors, on the other side of the user's house, or otherwise unable to see the cooker.

SUMMARY OF THE INVENTION

The present invention satisfies the needs and alleviates the problems discussed above.

In one aspect, there is provided an outdoor system for cooking food, smoking food, or a combination thereof comprising: (a) an outdoor cooking and/or smoking unit having an interior; (b) one or more heating elements in the interior of the outdoor cooking and/or smoking unit; (c) a control unit located within or on the outdoor cooking and/or smoking unit which includes or is electronically coupled with a GPS receiver or other GPS locating element and is enabled to activate and/or control least one operation of the outdoor cooking and/or smoking unit; and (d) a hand-held wireless device which includes or is electronically coupled with a GPS receiver or other GPS locating element and wirelessly communicates with the control unit, either directly or through a remote server or other cloud system, to remotely instruct the control unit to activate and/or control the least one operation of the of the outdoor cooking and/or smoking unit. The control unit, the hand-held wireless device, the server or other cloud system, or a combination thereof automatically determines whether the hand-held device is within a predetermined GPS distance of the outdoor cooking and/or smoking unit so that the control unit is prevented from activating and/or controlling the at least one operation of the outdoor cooking and/or smoking unit if the hand-held wireless device is located beyond the predetermined GPS distance from the outdoor cooking and/or smoking unit.

Examples of preferred hand-held devices 101 include, but are not limited to, smart phones or tablets which are app enabled for communicating with the control unit 125 located in or on the outdoor cooking and/or smoking unit 102 through Bluetooth, Bluetooth Login Energy, Wi Fi or some similar wireless RE protocol, or a hand-held remote specifically designed to work with the outdoor cooking and/or smoking unit using an infrared modulated signal.

The control unit 125 of the outdoor cooking and/or smoking unit 102 can include any desired type and/or number of components wherein, for example (a) the components comprise separate, electronically linked modules which are located together in the outdoor cooking and/or smoking unit 102 or (b) the components comprise separate, electronically linked modules wherein one or more of the modules is/are installed at different locations in the inventive cooking system 100, or (c) the components are located together and electronically linked on a single circuit board located in or on the outdoor cooking and/or smoking unit 102, or (d) the components are otherwise located together in a single piece of hardware positioned in or on the outdoor cooking and/or smoking unit 102. Consequently, it will be understood that one or more of the components of the control unit 125, and/or the functions thereof, can alternatively be located or performed in the World Wide Web using the remote server or other cloud system 139 or can alternatively be located or performed in the hand-held device 101.

As illustrated FIG. 4, the control unit 125 includes a GPS receiver or other GPS locating element 141 which is located in or on the outdoor cooking and/or smoking unit 102 for the purpose of determining the GPS position of the outdoor cooking and/or smoking unit 402. The control unit 125 preferably also comprises: a microprocessor or other computer processing unit 140, a computer readable medium, device, or other storage component 142 which is readable by the processing unit 140; a battery 144 and/or a power cord for powering the control unit 125 and the other electrical components of the automated system 100; and a Bluetooth, radio frequency, infrared, Wi-Fi, and/or other wireless communication module 146 for wirelessly receiving communication signals from and wirelessly sending communication signals to the hand-held device 101 either (a) directly, (b) via the remote server or other cloud system 139, or (c) both.

In order to receive additional status and operational information regarding the outdoor cooking and/or smoking unit 102 and to execute programmed instructions, the control unit 125 is preferably also electronically linked, using wireless, wired, circuit board, or other connections, to the burner

gas control valves

126 a, 126 b, and 126 c, the igniter 113, the one or

more condition sensors

117 a, 117 b, 117 c and/or 117 d, and the manual enabling element 132. The control logic and other programmed instructions (illustrated in the flow chart of FIG. 5) for the control unit 1 are preferably embodied (i.e., stored) on the computer readable storage component 142 of the control unit 125 in the form of a program code which is readable by the processing unit 140 to cause the control unit 125 to automatically perform, activate, and/or control certain operations and functions.

In one such operation, the control unit 125 of the inventive system 100 automatically determines whether the hand-held device 101 is currently positioned within or beyond the boundary limit 14 of a figurative “geo-fence” around the outdoor cooking and/or smoking unit 102. The geo-fence boundary limit 14 can be any preselected radial GPS distance 150 from outdoor cooking and/or smoking unit 102. In accordance with the programmed procedure of the inventive system 100, if the hand-held device 101 is currently located beyond the preselected GPS distance 150 from outdoor cooking and/or smoking unit 102, the control unit 125 will be prevented by the programmed procedure from complying with a remote instruction from the hand-held device 101 to automatically activate and/or control at least one operation of the outdoor cooking and/or smoking unit 102. However, on the other hand, if the hand-held device 101 is currently within the preselected GPS boundary distance 150 from the outdoor cooking and/or smoking unit 102, the control unit 125 will not be prevented, at least by the GPS distance determination, from performing the operation in question in accordance with the remote instruction received from the hand-held unit 101. The control unit 125 may send a signal to the hand-held unit 101 to activate a display informing the user that the hand-held unit 101 is inside or outside of the goo-fenced boundary limit 148.

In order to allow the control unit 125 to determine the current GPS distance of the hand-held unit 101 from the outdoor cooking and/or smoking unit 102, the GPS location of the hand-held unit 101 can be automatically transmitted to the control unit 125 by the hand-held unit 101. Alternatively, the control unit 125 can be programmed to track the GPS location of the hand-held unit using, e.g., an internet GPS tracking app which operates via the remote server or other cloud system 139.

The preselected radial GPS distance 150 of the geo-fence boundary 148 from the outdoor cooking and smoking unit 102 can be any distance suitable for ensuring a desired closeness of the user or line-of-sight view of the outdoor cooking and/or smoking unit 102 when remotely performing the operation(s) in question. Also, the programmed geo-fence boundary distance 150 for permitting some remote operations can be farther or closer than the distance permitted for others.

By way of example, in accordance with a programmed procedure of the inventive outdoor system 100 for remotely igniting the

burner elements

112 a, 112 b, and 112 c of the outdoor cooking and/or smoking unit 102, the radial GPS distance 150 of the geo-fence boundary 148 from the cooking and/or smoking unit 102 will preferably be not more than 10 meters and will more preferably be not more than 5 meters. In other words, if the preselected geo-fence boundary distance 150 is 5 meters and the current distance of the user, or more accurately the distance of the hand-held device 101, is more than 5 meters from the outdoor cooking and/or smoking unit 102, the user will not be permitted to remotely ignite the

burner elements

112 a, 112 b, and 112 c. On the other hand if the distance of the hand-held device 101 from the outdoor cooking and/or smoking unit 102 is 5 meters or less, the programmed geo-fence distance 150 determination performed by the control unit 125 will not prevent the user from remotely igniting the

burner elements

112 _a,112 b, and 112 c.

Consequently, if, in accordance with the programmed procedure, the control unit determines that the handheld device 101 is within the geo-fence boundary distance 150, and assuming that there or no other program restrictions barring such operation, the control unit 125 will comply with the remote instruction received from the user to start the cooking and/or smoking unit 102 by (1) first opening the burner

gas control valves

126 a, 126 b, and 126 c and then (2) activating the igniter 113 to ignite the

burner elements

112 a, 112 b, and 112 c.

However, prior to starting the outdoor cooking and/or smoking unit 102, in accordance with another aspect of the inventive system 100 which is preferably included in the program code of the control unit 125, the control unit 125 can also automatically determine whether at least one sensed condition of the outdoor cooking and/or smoking unit 102, as communicated to the control unit 125 from the

condition sensors

117 a, 117 b, 117 c and/or 117 d, and/or by the manual enabling element 132, satisfies a predetermined criterion of acceptability. If the sensed condition does not satisfy a predetermined criterion of acceptability, the control unit 125 will not open the

fuel valves

126 a, 126 b, and 126 c and will not activate the at least one igniter 113 to ignite the one Or more gas fuel burners or

burner elements

112 a, 112 b, and 112 c, regardless of whether the hand-held wireless device 101 is located within the predetermined geo-fence distance 150 from the outdoor cooking and/or smoking unit 102.

As an example of one such predetermined criterion for allowing the user to remotely ignite the

burner elements

112 a, 112 b, and 112 c and/or remotely perform other operations, the sensor 117 a senses whether the lid, door, or other cover 106 of the cooking and/or smoking unit is closed. In this programmed scenario, if the lid 106 is closed, the control unit 125 will be prevented from igniting the

burner elements

112 a, 112 b, and 112 c (and/or activating or controlling one or more other operations) regardless of whether the hand-held wireless device 101 is located within the predetermined geo-fence distance 150 from the outdoor cooking and/or smoking unit 102.

The sensor 117 a will preferably be a magnetic proximity device having corresponding elements positioned on the cooker housing 104 and the lid or other cover 106. Alternatively, examples of other sensors which can be used for determining whether the door, or other cover 106 has been closed include, but are not limited to, mechanical plungers and optical encoders.

As an example of another predetermined criterion for allowing the user to remotely ignite the

burner elements

112 a, 112 b, and 112 c and/or remotely perform other operations, the control unit 125 can determine whether it is receiving or has received a signal from the manual enabling clement 132 indicating that the manual enabling element 132 on the cooking and/or smoking unit 102 has been manually activated by the user. Examples of suitable manual enabling elements 132 include, but are not limited to, electronic push buttons, rocker switches, knobs, or touch screen elements.

A requirement that the user must activate a manual enabling element 132 on the cooker and/or smoker 102 before one or more operations can be performed remotely helps to farther ensure that the user has seen and verified the current condition of the cooker and/or smoker 102 and is in sufficient proximity thereto. In this programmed scenario, if the user has not manually activated the manual enabling element 132, the control unit 105 will be prevented from igniting the

burner elements

112 a, 112 b, and 112 c (and/or activating and/or controlling one or more other operations) regardless of whether the hand-held wireless device 101 is located within the predetermined geo-fence distance 150 from the outdoor cooking and/or smoking unit 102.

burner elements

112 a, 112 b, and 112 c and/or remotely perform other operations, the sensor 117 b can he a weight sensor under the fuel container 130, or other suitable sensor, which will send information to the control unit 125 which allows the control unit 125 to determine whether the fuel container 130 contains at least a predetermined minimum amount of fuel, in this programmed scenario, if the fuel supply container 130 does not contain at least the predetermined minimum amount of fuel, the control unit 125 will he prevented from igniting the

burner elements

112 a, 112 b, and 112 c and/or remotely perform other operations, the sensor 117 c attached to the exterior of the outdoor cooking and/or smoking unit 102 is a horizontal proximity sensor which senses whether a wall of the user's home, a fence or any other structure is located within a predetermined horizontal distance of the cooking and/or smoking unit 102. In this programmed scenario, if any other structure is located within the predetermined horizontal distance from the outdoor cooking and/or smoking unit 102, the control unit 125 will be prevented from igniting the

burner elements

Similarly, as an example of another predetermined criterion for allowing the user to remotely ignite the

burner elements

112 a, 112 b, and 112 c and/or remotely perform other operations, the sensor 117 d attached to the exterior of the outdoor cooking and/or smoking unit 102 is a vertical proximity sensor which senses whether a patio cover, awning, any other structure is located within a predetermined vertical distance directly above the cooking and/or smoking unit 102. In this programmed scenario, if any other structure is located within the predetermined vertical distance above the outdoor cooking and/or smoking unit 102, the control unit 125 will be prevented from igniting the

burner elements

Examples of

suitable proximity sensors

117 c and 117 d include, but are not limited to, laser sensors, ultrasonic sonar sensors, cameras with autofocusing ranging technology and the like.

An alternative embodiment 200 of the inventive outdoor cooking system is illustrated in FIG. 6. The inventive cooking system 200 is identical to the outdoor cooking system 100 illustrated in FIGS. 1-5 except that in the inventive system 200, the control unit 125 is not electronically linked to each of the

gas Control valves

126 a, 126 b and 126 c of the

individual burner assemblies

110 a, 110 b, and 110 c but instead operates single master valve 202 installed in the main fuel line 124 upstream of the individual valves 126 a 126 b, and 126 c. Consequently, in each of the activation a ad control scenarios discussed above, when the hand held device 101 is located within the geo-fence boundary distance 150 and any and all other criteria of the programmed procedure are met, the control unit 125 will respond to a remote instruction from the hand-held unit 101 to start the outdoor cooking and/or smoking unit 102 by opening the master valve 202 and then activating the igniter 113 to ignite the burner elements 112 a 112 b, and 112 c.

In one scenario for allowing the master valve 202 to be used in this manner to ignite the

burner elements

112 a, 112 b, and 112 c, the programmed procedure executed by the control unit 102 can include the preliminary steps, for example, of requiring that the user first (a) manually actuate the manual enabling element 132, which will then cause the control unit 125 to place the master valve 202 in closed position awaiting remote activation and (b) manually open the

individual burner valves

126 a, 126 b, and 126 c. Alternatively, in an example of another programmed scenario, the control unit 102 can include the step of requiring that the user first manually open the lid, thus activating the sensor 117 a which will then cause the control unit 125 to be enabled to respond to a command to open the master valve 202.

The master valve 202 can be any type of electric valve capable of automatically opening and shutting off the flow of gas fuel in the manner described. Examples of suitable electric control valves include, but are not limited to, electric solenoid valves, electric proportioning solenoid valves, motor driven linear or rotary valves, or variable pressure controlling devices.

Thus, the present invention is well adapted to carry out the objects and attain the ends and advantages mentioned above as well as those inherent therein. While presently preferred embodiments have been described for purposes of this disclosure, numerous changes and modifications will be apparent to those in the art. Such changes and modifications are encompassed within this invention as defined by the claims.
